Strategic spatial analysis of urban greenbelt plans in Mashhad city, Iran
Abstract Background Greenbelt, known as the most restrictive form of urban containment policy, is a geographical boundary around a city or urban region to prevent urban sprawl. In the present study, the urban greenbelt plans were investigated with spatial, temporal, and statistical attitudes in Mash...
Evaluation of various image classification techniques on Landsat to identify coral reefs
Coral reefs are one of the prominent marine ecosystems in the world. Coral reefs are facing threats from both natural and anthropogenic factors. Monitoring, protecting and studying these ecosystems are considered as a complex process because they are underwater features. Remote sensing can be quite...
Modeling land use dynamics in the Kesem sub-basin, Awash River basin, Ethiopia
Nowadays, the land use and land cover change and its impacts are revealing on different natural resource and man-made systems. This study attempted to examine the land use and land cover (LULC) dynamics on this using multi-spectral satellite imageries in Geographical Information System (GIS) in the...
Afforestation of Transformed Savanna and Resulting Land Cover Change: A Case Study of Zaria (Nigeria)
This paper presents the effects of actions aiming at tree planting, and thus protection of the land belonging to Ahmadu Bello University (ABU) in Zaria (Nigeria) from erosion. This area is located within the northern limits of the Guinea savanna belt, which has been considerably transformed primaril...
Leveraging Multi-Source Data and Digital Technology to Support the Monitoring of Localized Water Changes in the Mekong Region
The limited availability of high-resolution monitoring systems for the drought phenomena and water dynamics affected by weather anomalies hinders policy decisions in a multitude of ways. This paper introduces the availability of the high-resolution Water Monitoring System (WMS) developed from a mix...
Identification of Shift in Sowing and Harvesting Dates of Rice Crop (<i>L.</i> <i>Oryza sativa</i>) through Remote Sensing Techniques: A Case Study of Larkana District
The present study aimed to determine the impact of climate variability on rice crops in terms of sowing and harvesting dates and crop period. The identification of sowing and harvesting dates were spotted by mask identification, variations in land surface temperature (LST) on a temporal scale in the...
